THE IRON INDUSTRY.
Fayette County, Pennsylvania, which includes the Connellsville beds. The output of Durham is not known accurately, as no statistics are kept in England of this material.
The Euhr raises half of all the bituminous coal raised in Germany, and makes two-thirds of the coke, and, in addition to supplying western Germany, sends coke to other countries. In 1899 Germany exported 750,000 tons of coke to France and 135,000 tons to Belgium, almost all of this coming from Westphalia. Austria received 600,000 tons, but part was from Silesia. The product of the Westphalian ovens, however, is so much better than the eastern supply that it is carried in large quantities as far as Styria in southern Austria, In 1892 the Euhr district made 66 per cent, of all the coke made in Germany, but in 1900 its share had risen to 75 per cent. This increase in rank as a coke producer has gone on with, remarkable regularity, as shown in Table XXIV-F.

The exports to Belgium are balanced by coke brought into Luxemburg from that country, the amount so imported being greater than the amount going from Westphalia to Liege. Only a small proportion of the furnaces in Luxemburg import coke, and the amount sent from the Euhr to Lothringen and Luxemburg in 1899 amounted to 2,783,000 tons, or nearly 40 per cent, of the coke production of Westphalia.
The coal occurs in a great number of beds, the number of workable seams being over two hundred, but none over six feet thick and the average only half that. The thickness of the coal measures
